Help for Mercenary Mastery DAIL Mod.

I am currently using Nightblade + Mercenary and i respeccted all my points to try and get some AoE from Mercenary from Blood and Steel because of the proc effect. But i don’t notice my damage increasing at all from it at max level 12/12 it says i should have about 345% main hand and offhand damage but there is no increase i have noticed, and the bleed on it is supposed to be 2560 damage over 8 seconds but the bleed is hitting for 170 damage a second for 8 seconds.

First post in forums; if i’m in the wrong topic sorry.
All pictures are in there.
